To complete this you need to eat one of each of the "good" foods found on the floors. Good food restores some of your health. Here are all the foods you must eat and on which floor in Fixed Mode I found them;

-Fudge Sundae - Floor 2
-Fries - Floor 2
-Pizza - Floor 3
-Cherry Pie - Floor 4
-Pancakes - Floor 4
-Cereal - Floor 6
-Bacon & Eggs - Floor 6
-Hamburger - Floor 7
-Fudge Cake - Floor 9
-Watermelon - Floor 11
-Candy Cane - Floor 11
